transcode_system_migration.sql

/*
This script migrates as much configuration as possible from the old transcode system to the new transcode system.

Assumptions:
	- This script is run against a 5.10 environment
	- No manual changes have been made to any formats after upgrading the targeted environment to 5.10.

Things to be aware of:
	- Since this script changes the configuration of the targeted environment,
	  please ensure that you handle the changes in Configuration Management after having run this script.



If a format doesn't have any conditions specified on when it should be created in the old transcode system
it will be allowed to be created in all cases in the new system. To identify these formats you can use the
following script. The script can be run after the migration too to identify the "bad" formats for cleanup
should that be desired.
